CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 15/645,452 filed Jul. 10, 2017, which claims the benefit of U.S. Provisional Application No. 62/359,729, filed on Jul. 8, 2016. The entire disclosure of each of the above applications is incorporated herein by reference.

FIELD

The present disclosure relates to vending machines and more particularly to a system for improving the frequency of monitoring a distributed set of vending machines.

BACKGROUND

This section provides background information related to the present disclosure which is not necessarily prior art.

Vending machines are point of sale locations where a retail transaction is completed, for example, using a machine to conduct the transaction. The vending machine, an amount due from the customer for the goods or services to be purchase is calculated, options for payment are provided, and a receipt for the transaction is issued. Typical point of sale vending machines are provided with dedicated terminals for self-service checkout, thereby lacking flexibility of use.

In addition, inventory management presents a challenge for businesses. Efficient inventory management requires oversight of the continuous flow of product into and out of an existing inventory. The management of inventory at a vending machine is difficult and presents an expense because a human is typically required to manage inventory and monies collected by the vending machine. Managing inventory typically requires one or more employees to dedicate time to physically locate and count product on hand, generate inventory reports, place purchase orders to replenish stock, and track the orders.

DETAILED DESCRIPTION

The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.

FIGS. 1 and 2 represent systems for monitoring vending machines according to the present teachings. Shown in the figures is a system 10 for monitoring a vending machine 12, a plurality of connected vending machines or a micromarket (all of which are herein labeled throughout a vending machine). The system can include what can loosely be thought of as containing a mesh network. The vending machine 12 includes a controller 14 and associated memory 16 configured to store information associated with the condition of the vending machine 12. The vending machine 12 also has a first short range transceiver 18 configured to transmit the information associated with the condition of the vending machine 12, a first distance D1. A plurality of mobile devices 20A and 20B each having a second short range transceiver 22 and a first long range transceiver 24. The mobile devices 20A are configured to receive information associated with the condition of the vending machine and transmit it via the first long range transceiver 24. A second long range transceiver 28; is associated with a server 30 coupled to the second long range transceiver 28. The server 30 is configured to receive the information associated with the condition of the vending machine 12, and transmit it to a system monitor 32 who is responsible for the maintenance and filling of a plurality of vending machines 12 located at different places.

Each mobile device has a software program which includes a circuit configured to facilitate a transaction of information between the vending machine 12 and the server 30. In this regard, the circuit is configured, optionally through the use of software, on the mobile device 20A to communicate with the vending machine controller 14 to transfer information through the mobile device to the server using the long and short range transceivers 18, 22, 24 and 28.

The software can be in the form of game or a digital wallet which facilitates the purchases at the vending machine. The digital wallet can store value for use with the machine or machines 12 and also can facilitate credit card purchases through the machine. The consumer facing wallet can accept payments using credit cards, or PayPal™. Additionally, as described below, the mobile device can be used to incentivize the user to move to with the Distance D1 to facilitate the transfer of data from the Vending machine to the server using messages sent to the user through the use of the long range transmitters and the software or circuit in the mobile device.

As the system is most efficient when information about the status of the machine is updated at regular pre-determined times, the server 30 is configured to monitor the timing of information retrieved through the system. In the event that data is not transmitted at regular intervals, the server 30 is configured to send a signal to a subset of the plurality mobile device 20A to induce a user to transport the mobile device to be transported to within the first distance from the vending machine. In this regard, the server can be configured to send a signal to an offer for a free or reduced price product from the vending machine. Additionally the server can send a signal with can be a piece of information that may be useful in for instance a game.

Once the user is within the distance D1 from the vending machine, the mobile device will facilitate the transfer of the vending machine status information in the form of a file such as a DEX file. The Short range transceiver can be for example a bluetooth enable system. The system can be associated with Micromarket systems where goods are sold via an un-attended terminal.

The server is a block diagram of an exemplary digital device. The digital device comprises a processor, a memory system, a storage system, a communication network interface, an I/O interface, and a display interface communicatively coupled to a bus. The processor is configured to execute executable instructions (e.g., programs). In some embodiments, the processor comprises circuitry or any processor capable of processing the executable instructions.

The memory system is any memory configured to store data. Some examples of the memory system are storage devices, such as RAM or ROM. The memory system may comprise the cache memory. In various embodiments, data is stored within the memory system. The data within the memory system may be cleared or ultimately transferred to the storage system.

The storage system is any storage configured to retrieve and store data. Some examples of the storage system are flash drives, hard drives, optical drives, and/or magnetic tape. The storage system may comprise non-transitory media. In some embodiments, the digital device includes a memory system in the form of RAM and a storage system in the form of flash data. Both the memory system and the storage system comprise computer readable media which may store instructions or programs that are executable by a computer processor including the processor.

The communication network interface (com. network interface) may be coupled to a network (e.g., network) via the link. The communication network interface may support communication over an Ethernet connection, a serial connection, a parallel connection, or an ATA connection, for example. The communication network interface may also support wireless communication (e.g., 802.11 a/b/g/n, WiMax). It will be apparent to that the communication network interface may support many wired and wireless standards.

The optional input/output (I/O) interface is any device that receives input from the user and output data. The optional display interface is any device that is configured to output graphics and data to a display. In one example, the display interface is a graphics adapter. It will be appreciated that not all digital devices comprise either the I/O interface or the display interface.

The hardware elements of the digital device are not limited to those depicted in FIG. 2. A digital device may comprise more or less hardware elements than those depicted. Further, hardware elements may share functionality and still be within various embodiments described herein. In example, encoding and/or decoding may be performed by the processor and/or a co-processor, such as a processor located on a graphics processing unit (GPU).

FIG. 3 represents a portion of the system shown in FIGS. 1 and 2. The system can be based on a Linux based computing platform. This platform can be retrofitted inside any vending machines and interfaces with the vending machine software protocol MDB/DEX. The telemetry device module has 4× USB ports to connect peripheral components (USB Bluetooth/WiFi dongle). Primary the telemetry device will communicate to a smartphone, described above as a 20A and 20B via Bluetooth/Wi-Fi, to an instruction set loaded into the smartphone. Using this mobile based software app the end-user can push a credit to the vending machine to purchase products. This software is configured to send a signal to the telemetry device which pushs a DEX handshake from the telemetry device to the vending machine controller. After the sending of the DEX handshake, the vending machine controller transfers the DEX file to the telemetry device. The telemetry device then sends data from the DEX file to the smartphone 20A, 20B via a short range transceiver such as Bluetooth or WiFi. This DEX file is then sent to the server via the long range transceiver.

The telemetry device further has a 2-way communication system which gives cash/cashless sales which need an MDB code to allow for selection mapping. The telemetry device further has a service application which allows for the setup, configuration, and the download of DEX files. Further, the telemetry device listens to the market application to give credit to the vending machine, send over transaction data, and send DEX data.

The device 20A has software which allows the ability to setup and account and to load money into the account. The software further is configured to allow the input of a coupon. Optionally, the smartphone will allow a planogram of items from the vending machine.

FIG. 4 represents a block diagram of the telemetry device shown in FIGS. 1-3. The Telemetry device can be a Linux based computing platform which can be retrofitted using adaptive cabling inside vending machines having vending machine software protocol MDB/DEX. The telemetry device has 4× USB ports to connect peripheral components (USB Bluetooth/WiFi dongle). As descried above, the telemetry device will communicate to a smartphone via Bluetooth/Wi-Fi to smartphones through a software application stored on the smart phone. These applications will receive information from the telemetry module and store it in memory on the smart phone device. This data (for example the DEX data) will be forwarded using the long distance transceiver, through the telephone networks. Using a mobile based software application the end-user can push a credit to the vending machine to purchase products. The block diagram shows major building blocks of the telemetry device. Shown is the vending machine interface (DEX/MDB) to the Android processor connection. These building blocks shall be integrated on the main PCB as much as possible.

FIG. 5 represents a flow chart describing the flow of information shown in FIGS. 1-4. The mobile device 20 a scans using Bluetooth or Wi-Fi for connectable devices on the service. In the event that no vending machines or devices are in the area, the app will attempt to entice the user to approach a machine. In this regard, the device may show the location of the closest machine, or offer a coupon or free product as described above. Secondarily, if a vending machine is available, the mobile device 20 a will forward a Device ID and encrypted authentication key. At this point, a handshake between the mobile device 20 a and the telemetry device occurs with a packet send/receive. The telemetry Packets are stored locally and sent to servers upon internet connection from the mobile device. To increase the speed of transmission, the packets can be sent out on multiple addresses and reassembled. To update software on either the mobile device or the telemetry device, portions of the updated software can be sent through the telecommunications system and the near field transceiver. These portions can be reassembled and installed.

The broad teachings of the disclosure can be implemented in a variety of forms. Therefore, while this disclosure includes particular examples, the true scope of the disclosure should not be so limited since other modifications will become apparent upon a study of the drawings, the specification, and the following claims. It should be understood that one or more steps within a method may be executed in different order (or concurrently) without altering the principles of the present disclosure. Further, although each of the embodiments is described above as having certain features, any one or more of those features described with respect to any embodiment of the disclosure can be implemented in and/or combined with features of any of the other embodiments, even if that combination is not explicitly described. In other words, the described embodiments are not mutually exclusive, and permutations of one or more embodiments with one another remain within the scope of this disclosure.

Spatial and functional relationships between elements (for example, between modules) are described using various terms, including “connected,” “engaged,” “interfaced,” and “coupled.” Unless explicitly described as being “direct,” when a relationship between first and second elements is described in the above disclosure, that relationship encompasses a direct relationship where no other intervening elements are present between the first and second elements, and also an indirect relationship where one or more intervening elements are present (either spatially or functionally) between the first and second elements. As used herein, the phrase at least one of A, B, and C should be construed to mean a logical (A OR B OR C), using a non-exclusive logical OR, and should not be construed to mean “at least one of A, at least one of B, and at least one of C.”

In the figures, the direction of an arrow, as indicated by the arrowhead, generally demonstrates the flow of information (such as data or instructions) that is of interest to the illustration. For example, when element A and element B exchange a variety of information but information transmitted from element A to element B is relevant to the illustration, the arrow may point from element A to element B. This unidirectional arrow does not imply that no other information is transmitted from element B to element A. Further, for information sent from element A to element B, element B may send requests for, or receipt acknowledgements of, the information to element A.

In this application, including the definitions below, the term ‘module’ or the term ‘controller’ may be replaced with the term ‘circuit.’ The term ‘module’ may refer to, be part of, or include processor hardware (shared, dedicated, or group) that executes code and memory hardware (shared, dedicated, or group) that stores code executed by the processor hardware.

The module may include one or more interface circuits. In some examples, the interface circuits may include wired or wireless interfaces that are connected to a local area network (LAN), the Internet, a wide area network (WAN), or combinations thereof.

Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.

When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In the foregoing description, the teachings have been described with reference to specific exemplary embodiments thereof. It will be apparent to those skilled in the art that a person understanding these teachings may conceive of changes or other embodiments or variations, which utilize the principles of these teachings without departing from the broader spirit and scope of the teachings. The specification and drawings are, therefore, to be regarded in an illustrative rather than a restrictive sense.
